Abstract

Abstract: Rate and equilibrium constants for the reactions of Pyronin, 3, 6-bis (dimethylamino) xanthylium cation, and of Thiopyronin, 3, 6-bis (dimethylamino) thioxanthylium cation, with several anionic and amine nucleophiles in water and methanol solutions have been determined. Rate and equilibrium constants for corresponding reactions of the two cations are quite similar, but small effects that may be attributed to ...
